From September 1931:
Clark Gable is playing opposite Greta Garbo in her new picture. One day at lunch he was approached by an ambitious reporter. “How do you find Miss Garbo?” he was asked.
“I don’t,” said Clark. “She is always on the set ahead of me.”
And what’s more–they say Clark isn’t a bit “scared” of Greta like most of the other leading men who have played opposite her.
